A catalytic C(sp2)–F bond carboxylation with CO2 is reported; the reaction is enabled by dual photoredox/palladium catalysis and involves a crucial fluoroalkenyl radical intermediate.

The scope of the synthesis of α-fluoro-unsaturated acids from aliphatic and aromatic aldehydes and diethylfluoro-oxaloacetate has been studied. α-Formyl derivatives of ketones and esters react in their aldehydic forms. 2-Fluoro-3-(2-thienyl)acrylic acid could be nitrated, probably in the 5-position of the thiophen ring. 2-Fluoro-3-(1-naphthyl)acrylic acid cyclized to 2-fluoro-4,5-benzinden-1-one (VIII)
